Lomeguatrib | MGMT inhibitor

Lomeguatrib (192441-08-0) is a potent (IC50 = 9 nM) inhibitor of O6-Methylguanine-DNA Methyltransferase (MGMT), an important DNA repair protein.1 It is currently being investigated in cancers that have acquired resistant to the chemotherapeutic temozolomide2-5, as well as other chemotherapeutics6,7.
